Abstract:
In order to ascertain the major agronomic traits correlated to the product of bitter melon，taking 15 new breeding combinations as materials，their agronomic traits in detail involved in stem，leaf，flower and fruit were investigated and analyzed.The results showed that there were 14 same agronomic traits among 31 traits.This indicated that these new combinations might have nearer genetic relationship.Correlation analysis on stem，leaf and total yield showed that leaf width and first female node both had significant negative correlation to total yield.HY1B had the highest yield because of its least first female node.The first female node of 4 new breeding combinations was below 13.Correlation analysis on flower，fruit and total yield showed that single fruit weight and pre-stage yield both had significant positive correlation to total yield，and the ration of female flower nodes was correlated significantly to commodity melon’s transverse and thickness.The results proposed a new breeding idea of taking first female node and single fruit weight as principal components used in selecting new breeding combinations in Momordica charantia.15 new breeding combinations were classified to 5 groups according to cluster analysis.Genetic relationship analysis showed that the filial generation traits were partial to their female parent，so selecting parents were very important for succeed breeding.More significance was found in selecting filial generations with more genetic relationship for further hybridation.
